Abstract

We evaluated the frequency of endometriosis among the patients who underwent laparotomy and studied retrospectively the frequency of endometriosis in Japanese women. The frequency of operation for endometriosis has been about 0.6% of all the new outpatients and 10.8% of patients with laparotomy. We found a higher frequency of endometriosis in the most recent period (1977–1979). The mean age of endometriosis patients was 40.74 + 0.65 (mean + SE) years old. Our results indicated that the frequency of endometriosis in Japanese women has increased during the last two decades.
